EDAC driver needs to look up attributes of NVDIMMs provided in SMBIOS. Provide a function that looks up an acpi_nfit_memory_map from a device handle (node/socket/mc/channel/dimm) and returns the SMBIOS handle. Also pass back the "flags" so we can see if the NVDIMM is OK. Acked-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com> Cc: "Rafael J.
